TL;DR of the paper, generated automatically.

Single-pass guidance for diffusion models, aiming to cut CFG's cost in half.

• Cost: CFG needs 2N forward passes for N steps. CtrlFlow needs one pass per step.
• Method: two LoRA adapters, 2.5% extra parameters each, on a frozen backbone.
• Scale: one checkpoint works at any guidance scale without retraining.
